Aṣta-sakhis

The beautiful larger than life size Sri Sri Radha Madhava, surrounded by Their Ashta-sakhis (eight principal gopi friends) — Sri Lalita, Sri Champakalata, Sri Chitra, Sri Tungavidya, Sri Vishaka, Sri Indulekha, Sri Rangadevi and Sri Sudevi, along with Gauranga Mahaprabhu and Giri-Govardhana.

I offer my respectful obeisances unto the lotus feet of my spiritual master and of all the other preceptors on the path of devotional service, unto all the Vaiṣṇavas and unto the six Gosvāmīs, including Śrīla Rūpa Gosvāmī, Śrīla Sanātana Gosvāmī, Raghunātha dāsa Gosvāmī, Jīva Gosvāmī and their associates. I offer my respectful obeisances unto Śrī Advaita Ācārya Prabhu, Śrī Nityānanda Prabhu and Śrī Caitanya Mahāprabhu, as well as all His devotees, headed by Śrīvāsa Ṭhākura. I then offer my respectful obeisances unto the lotus feet of Lord Kṛṣṇa and Śrīmatī Rādhārāṇī and all the gopīs, headed by Lalitā and Viśākhā.

2) In the middle of that lotus is a golden place surrounded by eight petals. On these eight petals the eight principal gopis reside, and in the center Lord Syamasundara and beautiful Srimati Radharani sit on a jewelled throne.

All the other gopīs help increase the joy of Kṛṣṇa’s pastimes with Rādhārāṇī. The gopīs act as the instruments of Their mutual enjoyment.
(CC Adi 4.217)

Thus Gadādhara Paṇḍita is simultaneously an incarnation of Śrīmatī Rādhārāṇī and Lalitā-sakhī.
(CC Adi 10.15 purport)

Information – It wasn’t until 1980, however, that Prabhupäda’s desire to see life-sized deities in Mäyäpur would come to fruition. Jananiväsa Prabhu takes up the story: “Big Rädhä-Mädhava were installed on Gaura-pürnimä of that year (1980). The temple was in the Lotus Building then, and They were worshipped there until 1986 (View Photo Album), when the first four gopis (Sri Lalita, Sri Champakalata, Sri Chitra, Sri Tungavidya) arrived. The other four (Sri Vishaka, Sri Indulekha, Sri Rangadevi and Sri Sudevi) arrived in 1992.”
